Energy-saving horizontal threshing

Model: AW9001~9008 Series
Application:
The product is used in the tobacco threshing and redrying line for separating lamina from stem of tobacco leaf by means of multi-stage mechanical threshing and multi-stage classifying, ensuring all indexes of separated lamina and stem meet certain technological requirements and the need for subsequent processing. The whole process is continuous and automatic.

Features:
- All materials conveying between different stages are by belt conveyors rather than air duct which can reduce degradation.
- Total length and area of energy saving horizontal threshing unit is much less than the traditional threshing unit.
- Total energy consumption of energy saving horizontal threshing unit is 30% less than the traditional threshing unit.
- It can process both the Virginia and Burley tobaccos while meet the desired quality indexes.
- Design and combination of thresher and pneumatic classifier in accordance with technology of gentle threshing and fine classifying, feature multi-stage threshing, gentle threshing, less threshing and multi-stage classifying and fine classifying, which can ensure good quality indexes.
- Its wiper feeder adopts double wiper structure which feature good balance and stable running. With dust suction port in the delivery end of wiper feeder which can reduce dust arisen from the falling of materials.
- Its storage feeder adopts the structure with reversed doffer which can ensure more uniform of material flow into subsequent equipment, adopts side chain drive structure to avoid belt off-tracking.
- Its tobacco splitter adopts structure of reversed doffer plus conveying belt (or doffer only), which can evenly divide tobacco leaves into equal parts. Its adjustment device adopts worm gear and worm for convenient and quick adjustment.
- Horizontal threshers in each stage adopts the latest gentle threshing technique and with rational and optimized threshing knife array, shape and size of baskets, rotating speed of threshing rotors as per different character of each stage. Shape and size of baskets and threshing knife spacing different from stage to stage to ensure large and medium size lamina ratio and threshing efficiency. Adoption of double-side threshing structure to enhance thresher utilization and reduce threshing rotor weight. More convenient for operation and repair with hand-operated device for opening the gate.
- Support rollers of belt conveyor and tobacco splitter with structure of spiral stretching roller for preventing belt off-tracking, and belt tensioning device adopts slide and slice rail structure for simple operation
- Pneumatic classifier is counter-flow with the structure of air blowing from the bottom, single thrower, large separating chamber, materials throwing angle is adjustable, which can ensure efficient and precise pneumatic classifying. Its conveying screening apron is drawer type for convenient of maintenance. The whole pneumatic classifier is combined structure combining pneumatic classifier, airlock, discharging belt conveyor, air duct and fan together, which can shorten the total length.
- Materials conveying between different stages is by belt conveyors and no need fan for materias pneumatic conveying, which can reduce total energy consumption.
- Adoption of circulating air in pneumatic classifying and conveying system which can effectively reduce
